I just read an interview on TheFutonCritic.com by a Producer.
At the end of the interview, he mentioned the "door scene".
He says: "In the end, Peterson teased one last moment that fans of "Smallville" (and I suspect Superman in general) will more than likely enjoy immensely. "There's a very good scene with a door," he said. "It's probably one of everybody's favorite scenes in the show... there's one shot that is just like the 'Smallville' shot. You'll see it and you'll be like 'This is what we needed in the finale!' You'll know it the second you see it...
Was he talking about the VERY LAST SCENE where Clark opens the door, rips open his shirt with the "S" as he walks to the camera? Or was he talking about something else? Just curious. It seems odd that he would give away the very last scene in the interview, although they did over-hype it. And what was the "Smallville shot" he talks about?
